Dynamic Periodic Table. Reactive Groups. Reactive groups are categories of chemicals that typically react in similar ways because they are similar in their chemical structure.
For purposes of predicting reactivity between mixed chemicals, each substance in CAMEO Chemicals has been assigned to one or more reactive groups, based on the known chemistry of that substance. If you can't find a chemical in the database--but you know what reactive group it belongs in--you can add the reactive group to MyChemicals instead in order to see the reactivity predictions. Global Instructional Chemistry.
Welcome to a new concept in the distributed teaching of Chemistry. Over the coming years, these pages will be built up to include small "stories" or case histories illlustrating modern chemistry in action, liberally dosed with "hyperactive" molecules which you will be able to rotate, measure and generally play with. The content will include chemical problems suitable for tutorial and classes, a page where you can log-in to suitable on-line information databases, pages where you can acquire programs and other software, and any other good ideas that people come up with. We expect these pages will be used to augment and enhance local courses rather then to replace their teachers!

Real-Life Chemistry Vol 3 - Physics Vol 1. An Interactive Periodic Table of the Elements. Chemistry Freeware. On this page I post reviews and links to freeware chemistry programs available for download at other sites around the internet.
All of the programs are ones that I have used, or currently use. None-the-less, I take no responsiblity for any problems you might experience as a result of installing any of these applications. Unless otherwise noted, the programs are for Windows systems. ACD/ChemSketch 12 Freeware. ACD continues to release updates to the outstanding Chemsketch freeware. Accelrys Draw is a program that allows you to generate structural formulas for complex molecules using a very intuitive drag-and-drop interface. No-fee Accelrys JDraw for academic and non-commercial use. Discovery Studio Visualizer 4. ChemAxon produces a wide range of Java-based chemistry tools, and they offer free academic licenses (you must register with them). Jmol is a free, open source molecule viewer for students, educators, and researchers in chemistry and biochemistry.
EniG. Chemical & Engineering News: What's That Stuff? You might ask yourself...
What's That Stuff? Ever wondered about what's really in hair coloring, Silly Putty, Cheese Wiz, artificial snow, or self-tanners? C&EN presents a collection of articles that gives you a look at the chemistry behind a wide variety of everyday products. Sort: Alphabetically (Text Only) | Most Recent. Metallic elements.

Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons. Once the tutorial has completely downloaded, a set of the arrows will appear that allow the user to increase or decrease the view magnitude in Manual mode. Click on the Auto button to return to the Automatic mode. Notice how each picture is actually an image of something that is 10 times bigger or smaller than the one preceding or following it.
